SASH PASTE-NEE.

Application filed July 16,

My present invention relates to casement windows, and my object is the provisionof a latching means for this type of windows which will'hold the same close to the sash to prevent the entrance of rain and wind therebetween.

A still further object is the provision of a means for this purpose which is automatically actuated upon the closing of the window.

To the attainment of the foregoing and other objects which will present themselves, the improvement also resides in certain other novel features of construction and operative association of parts, one satisfactory embodiment of which is disclosed by the accompanying drawings.

In the drawings:

Figure 1 is a vertical sectional view looking through a casement frame provided with a sash in accordance with this invention, the sash being in elevation.

Figure 2 is a horizontal sectional view showing the sash partly swung through the easement.

Figure 3 is an enlarged sectional View approximately similar to the showing in Figure 1.

Figure 4 is a sectional view approximately on the line 44 of Figure 3.

Figure 5 is a similar sectional view approx imately on the line 5-5 of Figure 3.

Figure 6 is a plan view of the plate carrying the hook engaging stud.

Figure 7 is a sectional view approximately on the line 77 of Figure 6.

In the drawings, a frame for a casement sash is indicated by the numeral 1 and a hinged sash therefor by the numeral 2. In carrying out my invention I rabbet the outer face of the outer vertical stile of the window sash, thus forming the same with a continuous groove 3. The top and bottom of the stile from the inner face thereof, is formed with notches and in these notches there are received plates 4, respectively, the said plate being fixed on the lower walls of the notches and covering the rabbet or groove 3. I arrange in the rabbet 3 a rod 5 whose ends project through suitable openings in the plates 4. Surrounding the lower portion of the rod 5 and received in the rabbet 3 there is a coil spring 6, one end of said spring being fixed to the rabbet and the other to the lower plate 4. In the notch at the top of the sash 2, and fixedly secured to the projecting end of the rod 1928. Serial No. 293,027.

or shaft 5 there is the inner. and rounded end ofa finger 8. This finger has its outer edge formed with a shoulder 9 that is in the path of engagement with a stop pin 10. Preferably and as disclosed k by Figure 4 of the drawings, the latching finger 8 comprises a straight body portion formed, as stated, with a rounded end provided with the shoulder 9, and through this rounded end there is passed a pin or pivot 11 that also passes through the upper end of this rod or shaft 5. In this connection it should be stated that the rod or shaft does not project beyond the pockets provided by the notches in which the plates 4 are secured. On the lower end of the rod or shaft 5 there is fixed by a pin or pivot 12 a curved metal member in the nature of a hook 13, and this hook, when the sash is brought into contact with the frame engages with a metal plate 14, which, of course, is fixed on the said frame. The frame on its upper and outer corner has secured thereon a plate best illustrated by Figures 6 and 7 of the drawings. This plate, indicated by the numeral 15, is centrally formed with, a depending headed lug 16 that is surrounded by a roller 17.

l Vhen the sash is swung outwardly on the frame, the spring 6 will influence the rod to bring the shoulder 9 against the stop pin 10 which arranges the straight finger 8 to one side of the stop element 17 of the catch. When the sash is swung fully home the rounded hook 13, traveling on the plate 14, will swing the shaft 5 against the pressure of the spring 6, causing the hook 8 to be brought directly behind and in contacting engagement with the stop element 17, and thereby effectively fastening the upper and outer corner of the sash and preventing the sagging thereof by the influence of wind and likewise holding the sash tightly against the frame to prevent the entrance of air, rain or sleet therebetween.

The simplicity of my improvement will be perfectly apparent to those skilled in the art to which such invention relates so that further detailed description will not be required. It is thought, however, necessary to state that I do not wish to be restricted to the precise details herein set forth and, therefore,

otally supported round hook, spring influenced away from the sash and designed to be brought against the sash when the latter is swung to closed position, a finger connected with the hook and influenced by the turning thereof, and a revoluble element on the easing to engage With the finger when the latter is swung by the hook.

2. The combination with a casement frame and 'a hinged sash therefor, said sash naving its stile at its outer edge, rabbeted and its inner corners notched, plates seated in the notches, a spring influenced shaft journ'aled through the plates, a linger on the upper end of the shaft received. in the upper notch, a stop element for the finger to limit the outward swinging thereof when the shaft is influenced by the spring, a curved element fixed on the shaft and arranged in the lower notch of the sash, a wear plate on the frame to engage with W'ILFRED A.
